Parasitism
While food availability plays a significant role in population growth, other factors such as disease, predation, competition for resources, and environmental changes also influence population size. A population can be limited by a combination of these factors, not just food availability.
Ostriches face limiting factors such as habitat loss due to human encroachment, hunting for their feathers, skin, and meat, as well as predation by large carnivores like lions and hyenas. Additionally, diseases and parasites can impact ostrich populations, affecting their overall health and survival.
The greatest limiting factor for plants that grow on the floor of a rainforest is often the lack of sunlight due to the dense canopy above. This results in limited light availability for photosynthesis, which is crucial for plant growth and survival. As a result, plants on the rainforest floor have adaptations to maximize light absorption, such as large leaves or growing towards small gaps in the canopy.
No. Natural selection works in all populations. However, new alleles spread more slowly in large populations; the large size has a stabilizing effect. So one should expect large populations to change more slowly than smaller populations.

Because there are more limiting factors that keep a population from growing too large.

when large populations starts to need higher supply of food and water so they start to compete.
A population with a low population density would be least likely to be affected by a density-dependent limiting factor, as these factors typically become significant when populations reach higher densities.
Yes, air quality can be a limiting factor for populations, especially in areas with high levels of pollution or low oxygen levels. Poor air quality can impact the health and reproduction of organisms, ultimately affecting population dynamics.
Yes it is true
If a population of gophers has grown so large that space is a limiting factor, there's a possibility the population will become extinct. Mammals need space to grow and survive.
A natural disaster is considered a density-independent limiting factor because its impact on a population does not depend on the population's size or density. Events such as hurricanes, earthquakes, and wildfires can affect large areas and populations regardless of how many individuals are present. This means that even in low-density populations, a natural disaster can cause significant mortality and disruption, leading to a decline in population numbers without being influenced by the population's density.
